Hi Robert, Thanks for your quick reply, good to know it can be done with osgVolume. I will explain the problem I am facing in detail now:
1. I have tried to load some dicom images (provided by a doctor here) with the following command: osgvolume --images *.dcm The images load without any issues, but the output I get is something like output_withouttf.jpg attachment. (The opener of this thread got something similar as I can see). 2. Then I tried to play around with the transfer function to generate something better. I downloaded some sample transfer functions from the following tutorial (they have a zip file with several sample transfer functions for bones, brain etc.): *link posted in next post* Since their example had some parameter like --tf-255 and osgvolume actually does not have any parameter like this, I converted all the values to be in between 0 and 1. From this forum I figured out that is how it should be, please correct me if I am wrong. The color-255.tf and my converted color.tf both are attached to this post. Then I executed a command as follows: osgvolume --images *.dcm --tf color.tf And I get an output like the attached output_withtf.jpg. I have tried some other color transfer functions too, but all the outputs are like this. I am guessing it has something to do with the way I am trying to normalize the transfer function? Please let me know if I am doing anything wrong. ... Thank you!
